Application mea May 31, 1923. serial No. 642,461.

To all whom t may concern:

Be itknown Ithat I, CHARLES H. LEINERT, avcitizen of the United States,residing `at Chi-cago, in the count-y of Cook and State of Illinois,have invented eertainnew and useful Improvements in Valves, lof whichthe following is a specification.

This invention relates to a new and im proved valve and `morespecifically to a check valve particularly adapted for use with blowerengines or air compressors or the like. i i

The present applica-tion is in the nature of an improvement on thedevice shown in my prior Patent No. 1,404,130, granted January 17,1922..

Valves of this type are operated at high speed andare repeatedly seatedand unseated in their operation'.` This speed and constant use causesconsiderable wear of the valve member. The valvel member in lmy priorconstruction was actuated by springs,

all of which extended -circumferentially in the same direction. Withthis form of construction, there is a tendency for a slight twistingmotion of the valve plate in its seating and unseating movement. Thistwisting tendency adds to the wear cause by the operation ofthe valve.

` It is an object of the present invention to provide a new and improvedvalve actuating spring construction for use in connection with valves ofthe character described.. y

It is a furtherwobject to provide a spring construction adapted tosupport aV valve member, the springs having ,fportions ex-` tending inopposite directions `whereby any twisting tendency is counteracted.

It is an additionalobjectl to p-rovide a spring construction whichvsupports the valve member in a manner to minimize sagI of the valve andto effectively cushion the valve seat `while atthes'ame time causing arapid unseating of the valve.

.Other and further objectswill the description proceeds.

appear as l have illustrated certain preferred embodiments of` myinvention in the accom4` panying drawings, in which:

Figure 1 is a transverse section of one form of valve; f Figure 2 is asection taken on line 2-2 of Figure l;

`the plate in proper relation `to Figure 3` is a section taken1 on line3 3 of'Figure 1;-and p Figure L11s a view tion. p .i .i l Y y The valveassemblyl as shown comprises the seat memberA, the abutment member B andthe valve member C, these three members being securedin adjustedrelation by means of collarllbolt E and nut F. The seatmember A,comprises the hub`11 from is supported by spokes 13. The portion`12 isprovided with the circumferential channels 14. The rim portion 15 issupported from portion 12 byspokes 16.

' The valve..member C as ybest shown in- Figure 3 is provided with thespaced circumferential Openings 17 lwhich register` with the groove leof the `seat member A. The valve member C is provided with thecentral'opening 18 which loosely fits about 'i the collar D.

The abutment member is'provided with similar to Figure .i 2: but showinga modliicdiormof construc` which the inner circumferential portion`12 lwith a circumferentially extending recess l 20 which has the inwardlyextending portions 21 extending in toward the hub between theopenings-19. y y l The springs 22 shown in Figure 2 have a .centralportion 23 which extends through a slot 24'in theabutmentmember B and issecured under the washer 25 which lits under the head of the bolt E. yThis washerl 25 is preferably Vformed of soft metal such as copper soythat lit deforms under pressure and thus rigidly .secures the lspringsin place. The springs 22'are provided with oppositely extending arms 26and 27 which are formed with a reverse y,bend so that their ends 28 and29 areadjacently located. It i willA be noted ythat :the `free ends ofthe spring arms aredirec'ted inwardlytoward the central securing portionof the vspring and that the valve member is thussupported at.pointsinwardly of its periphery, These ends V28 and 29 extend throughperforations in the valve plate C and retain the other members of theassembly. In the form' of construction shown in Fig y Go arms '32 and 33ivrhichertend approximately f circumferentially and are extendecgl, in,-xvardly and provided with up-turned ends 34 and 35y at points adjacentthe central portions of the adjacentsprings. .Each end 35 yof a springis located adjacent the-endflbl a similar spring. Vherethe spring armscross, the upper arm is curved' upwardly 'as indicated at `3e so thatthere'vvvillf'be n frictionalnviear between the two arms.` vr-I-hespring ends are 'secured to the'valve plate in a manner similar to thatshown in connecffiorvie traspasarmeer b otli forms ,of the device shown,the valve niet@ ssirreftd by resilient means wish" @aan a @page dreamsand which resist any renderer for'the' valrerbt Itotwist or ,have 'a'rota-ry motion about its axis. `The seatingy of the valve is thuslimitedtoA a direct reciprocvatory 'motion and Wear between i the -valve andvalve seat is minimised.
